  1. Patterns in subtidal seaweed communities on coral-dominated reefs at Sodwana Bay on the KwaZulu-Natal coast, South Africa

    Patterns in subtidal seaweed communities on coral-dominated reefs at Sodwana Bay on the KwaZulu-Natal coast, South Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    Subtidal seaweed communities of the northern coast of KwaZulu-Natal (KZN) have not been studied before. At Sodwana Bay, we tested the hypotheses that the seaweed communities would (1) differ floristically with depth, (2) be more species-rich in shallower water, (3)...
  2. Baseline assessment of high-latitude coral reef fish communities in southern Africa

    Baseline assessment of high-latitude coral reef fish communities in southern Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    The Western Indian Ocean (WIO) is a region where detailed coral reef fish research has been relatively limited. This study constitutes an assessment of the fish communities of seven southern African high-latitude coral reefs. The aim was to provide ichthyological...
  3. Comparing fish communities in sanctuaries, partly protected areas and open-access reefs in South-East Africa

    Comparing fish communities in sanctuaries, partly protected areas and open-access reefs in South-East Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    Fish were surveyed by visual census on offshore reefs in Mozambique and eastern South Africa to compare (a) fully-protected ‘sanctuary’ areas, (b) ‘partly protected’ areas where recreational diving and limited fishing are permitted, and (c) ‘open’ unprotected areas. Community composition...
  4. Spatial diversity of nematode and copepod genera of the coral degradation zone along the Kenyan coast, including a test for the use of higher-taxon surrogacy

    Spatial diversity of nematode and copepod genera of the coral degradation zone along the Kenyan coast, including a test for the use of higher-taxon surrogacy

    Item type: Journal Article • Journal: African Journal of Marine Science
    The biodiversity of meiofauna in the coral degradation zone along the Kenyan coast was examined with special emphasis on the most abundant taxa, Copepoda and Nematoda. Communities from three microhabitat types (coralline sediment, coral gravel and coral fragments) at two...
  5. Differential effects of thermal and chemical stressors on tissue balls from scleractinian corals

    Differential effects of thermal and chemical stressors on tissue balls from scleractinian corals

    Item type: Journal Article • Journal: African Journal of Marine Science
    Coral cell aggregates (tissue balls) from four species (Acropora muricata, Fungia repanda, Pavona cactus and Pocillopora damicornis) were used as an indicator to investigate the effects on the corals of thermal stress and of chemical extracts from three sponges (Adocia...
  6. Estimation of size at first maturity in two South African coral species

    Estimation of size at first maturity in two South African coral species

    Item type: Journal Article • Journal: African Journal of Marine Science
    The corals Acropora austera and Platygyra daedalea have been the subject of extensive reproductive and population genetic studies in the iSimangaliso Wetland Park (iSimangaliso), on the KwaZulu-Natal coast, eastern South Africa. Despite this, estimates of size at first maturity in...
  7. A <em>Porites lutea</em> climate record from Sodwana Bay, South Africa

    A <em>Porites lutea</em> climate record from Sodwana Bay, South Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    We report on a 41-year (winter 1970 to winter 2010) Porites lutea coral core climate record from Two-Mile Reef, Sodwana Bay, in the South-Western Indian Ocean. X-ray analysis, ultraviolet fluorescent photography and stable isotope (δ18O and δ13C) analysis revealed skeletal...
  8. Reef fishes recruited at midwater coral nurseries consume biofouling and reduce cleaning time in Seychelles, Indian Ocean

    Reef fishes recruited at midwater coral nurseries consume biofouling and reduce cleaning time in Seychelles, Indian Ocean

    Item type: Journal Article • Journal: African Journal of Marine Science
    In coral reef restoration, coral gardening involves rearing coral fragments in underwater nurseries prior to transplantation. These nurseries become fish-aggregating devices and attract biofouling. We hypothesised that: (1) the presence of corals at a nursery is critical to recruit fish...
  9. Spatio-temporal patterns of coral recruitment at Vamizi Island, Quirimbas Archipelago, Mozambique

    Spatio-temporal patterns of coral recruitment at Vamizi Island, Quirimbas Archipelago, Mozambique

    Item type: Journal Article • Journal: African Journal of Marine Science
    Spatial and temporal patterns of recruitment of reef corals were assessed for the first time in Mozambique by deploying settlement plates at various spatio-temporal scales between October 2012 and October 2013. The abundance of juvenile corals (5−50 mm in diameter) was...
  10. Influence of local environmental conditions and bleaching histories on the diversity and distribution of <em>Symbiodinium</em> in reef-building corals in Tanzania

    Influence of local environmental conditions and bleaching histories on the diversity and distribution of <em>Symbiodinium</em> in reef-building corals in Tanzania

    Item type: Journal Article • Journal: African Journal of Marine Science
    Pollution, turbidity and coral bleaching history, as well as coral diversity, vary along the Tanzanian coastline. Prior to this study, it was not known whether exposure to such environmental variation might have influenced the diversity and distribution of Symbiodinium along...
